Abstract
The utility model discloses an LED down lamp, which aims to be uniform in luminescence and avoid glaring. The LED down lamp comprises a hollow front frame, a circuit board, a diffuser plate, a rear shell and a radiator, wherein the circuit board is placed in the front frame, LEDs are arranged on the front surface of the circuit board, the diffuser plate is fixed at the front of a hollow portion of the front frame, the rear shell is fixedly connected with the rear surface of the circuit board and fixedly connected with the rear of the hollow portion of the front frame via screws, and the radiator is fixedly connected onto the rear shell via screws. The LED down lamp can be used for various illuminations, and is particularly suitable for commercial illumination for offices, marketplaces, subways, libraries, banks, hotels and the like.
Description
Technical field
The utility model relates to the LED light fixture, especially relates to a kind of LED Down lamp.
Background technology
LED (Light Emitting Diode, light emitting diode) extensive use in various lighting apparatus owing to have outstanding advantage such as energy-saving and environmental protection.As in Down lamp, useful LED replaces traditional fluorescent lamp, and it normally is provided with some LED on the planar circuit board in being arranged at housing, and the light that LED sends penetrates through the flat glass that LED plane lamp front surface is provided with.This kind light fixture is owing to replaced traditional fluorescent lamp with LED, and therefore, the traditional plane lamp that uses fluorescent lamp to do light source of its thickness is frivolous, and energy-conserving and environment-protective more.But these LED Down lamps are because luminous inhomogeneous of LED, and the light after penetrating through flat glass is also inhomogeneous, thereby make the brightness irregularities of LED Down lamp, are easy to generate dazzle.
The utility model content
The utility model provides a kind of LED Down lamp in order to solve prior art LED Down lamp brightness irregularities, to be easy to generate the technical problem of dazzle.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is a kind of LED Down lamp of design, comprise the preceding frame of a hollow and place the interior circuit board of preceding frame, described circuit board front surface is provided with LED, and described LED Down lamp also comprises: one is fixed in the diffuser plate of preceding frame hollow space front portion; One fixedly connected with the circuit board rear surface and by screw be fixedly connected on described before the back cover at frame hollow space rear portion; One is fixedly connected on radiator on the back cover by screw.
The rear end of frame extends back at least two holding sections before described, the terminal both sides of the described holding section boss that extends internally out more backward, described LED Down lamp comprises that also an elasticity buckles, described elasticity buckles has a spiral helicine spring portion by the wire coiled, and the boss of described holding section entangles in described spring portion.
Described radiator is provided with fin, and described fin is that the center is symmetrical distribution with the axis of LED Down lamp, and the deep side of each fin is made of at least two sub-fin.
The utility model is used for reference the operation principle of LCD by transforming the structure of traditional LED Down lamp, changes traditional plate glass into diffuser plate, thereby the light that LED is sent is very even through the light that penetrates after the effect of diffuser plate, can not produce dazzle.
Description of drawings
Below in conjunction with embodiment and accompanying drawing the utility model is elaborated, wherein:
Fig. 1 is the utility model LED Down lamp three-dimensional combination figure;
Fig. 2 is the utility model LED Down lamp three-dimensional exploded view.
The specific embodiment
See also Fig. 1 and Fig. 2, the utility model LED Down lamp comprises preceding frame 1, diffuser plate 2, circuit board 3, back cover 4 and radiator 5.Wherein, preceding frame 1 is the aluminum framework of a hollow, and diffuser plate 2 is fixed in preceding frame hollow space front portion, is used for that the light that LED sends is changed into uniform light and penetrates.Before can being fixed in by screw 8, on the frame, certainly, also can fix diffuser plate 2, as snap fit etc. by alternate manner.The concrete structure of diffuser plate 2 can to make the structure of diffuser plate in field identical with LCD.The front surface of circuit board 3 is provided with some LED, and it is fixed on the back cover 4 by screw 8.Back cover 4 is a heat conductivility good metal plate, and its front surface is fixedlyed connected by screw with the circuit board rear surface, and the rear surface is connected with radiator by screw, simultaneously, and the rear portion of the hollow space of frame 1 before back cover is fixedly connected on by screw 8.
The preceding frame 1 of one hollow and the circuit board that places in the preceding frame, described circuit board front surface is provided with LED, and described LED Down lamp also comprises: one is fixed in the diffuser plate of preceding frame hollow space front portion; One fixedly connected with the circuit board rear surface and by screw be fixedly connected on described before the back cover at frame hollow space rear portion; One is fixedly connected on radiator on the back cover by screw.
Before the rear end of frame 1 extend back at least two holding sections 11, the terminal both sides of described holding section 11 boss 12 that extends internally out more backward.The LED Down lamp comprises that also one buckles 13 with the elasticity of described holding section 11 couplings, and elasticity buckles 13 and has a spiral helicine spring portion 131 by the wire coiled, and the boss 12 that described holding section is entangled by spring portion 131 is realized and being connected of boss 12.
Because the light that sends of the utility model LED Down lamp LED is through after the diffusion of diffuser plate, the light that LED is sent is more even, thereby the uniformity of the utility model LED Down lamp is reached more than 80%, and is also more frivolous in dazzle no longer.Simultaneously, employing is divided into the plurality of sub fin at the side at the fin principle center of radiator, has strengthened radiating effect.
The utility model LED Down lamp can be used for various illuminations, especially is fit to commercial lightings such as office, market, subway, library, bank, hotel.
